[0045] In this way, the fixing process of the rear side of the coupling disc 4 is that the mounting hole on the coupling disc 4 and the threaded hole four on the second side plate 11 are aligned with each other, then the threaded part four 43 is first inserted through the mounting hole, and then is screwed into the threaded hole four, so as to complete the fixing of the rear side of the coupling disc 4, at this time, if reinforcement is needed, the nut is screwed into the free end of the threaded part four 43, so as to be further fixed.

[0046] The sliding process of the front side of the coupling disc 4 is that the arc-shaped slot 41 on the coupling disc 4 is corresponded with the threaded hole three on the second side plate 11, so that the threaded hole three falls within the range of the arc-shaped slot 41, then the threaded part three 42 is sequentially inserted through the arc-shaped slot 41 and is screwed into the threaded hole three, then the arc-shaped slot 41 is moved along the threaded part three 42, so as to slide the coupling disc 4, after adjusting to the corresponding position, the threaded part three 42 is screwed into the threaded hole three, so as to fix the coupling disc 4; during adjustment, only the threaded part three 42 needs to be loosened.

[0048] Further, as shown in Figures 1-2 and as shown in Figure 4 , the super bright waxing machine further comprises an encoder assembly 50, the encoder assembly 50 and the cross beam adjusting structure 30 are located on the second side plate of the cross beam 1, and the encoder assembly 50 is located on the rear side of the cross beam adjusting structure 30, the encoder assembly 50 comprises an encoder 51, a transmission gear 52, a fixed support 53 and an encoder seat 54, the second side plate 11 of the cross beam 1 is provided with a through hole 14, the encoder seat 54 is located in the through hole 14, the encoder 51 is fixedly installed on the encoder seat 54, and the input shaft of the encoder 51 is arranged in the transverse direction and faces the first side plate, and the encoder seat 54 is suspended in the through hole 14 through the fixed support 53, in detail, the encoder seat 54 is connected with the fixed support 53, the fixed support 53 is fixedly installed on the first side plate 11, the fixed support 53 can be installed on the first side plate 11 by screwing the screw and the screw hole, the connection structure between the encoder seat 54 and the fixed support 53 is fixedly connected in the existing conventional manner, for example, the two are fixed together by screwing the screw and the screw hole, and for example, the two are integrally connected; wherein the transmission gear 52 is tightly sleeved on the input shaft of the encoder 51, and the transmission gear 52 and the swing rack are mutually engaged.

[0049] During the longitudinal reciprocating movement of the cross beam 1, the transmission gear 52 moves synchronously with the cross beam 1, because the transmission gear 52 and the swing rack are mutually engaged, the transmission gear 52 rotates, thereby driving the input shaft of the encoder 51 to rotate, and then the encoder 51 detects, until the cross beam 1 stops moving, the encoder 51 can immediately stop due to the action of gravity, thereby improving the accuracy of the detection of the encoder 51, and when the cross beam 1 moves too fast in the longitudinal direction, the accuracy of the detection can still be ensured.

[0050] Further, as shown in Figures 5-6 The super-bright waxing machine further comprises two expansion sleeves 6, which are respectively arranged in one-to-one correspondence with the two swing gears 21.

[0052] In this way, the rotation of the swing transmission shaft 2 drives the swing gears 21 to rotate synchronously through the expansion sleeves 6. The arrangement of the splines ensures that the swing transmission shaft 2 and the swing gears 21 do not easily skid for a long time. It should be noted that the bolts on the two expansion sleeves 6 are respectively directed to the middle position of the swing transmission shaft 2 after installation.
